I have front end code written this way where on a button click, I need to get certain data from the node server to populate a map that I have on the client side. This map is displayed on : " http://localhost:8080/ "
My code to request from the server looks like this:
<div id="heatmap">
<input name="heatit" type="submit" value="Heat up!">
<script>
$("#heatit").click(function (){
$.ajax({
url:"/heatmap",
type: "POST",
success: function(result) {
console.log("hi");
}
});
});
</script>
</div>
And this is my server side code:
app.post('/heatmap', function(req, res) {
console.log("hey");
res.send(densityList);
});
When I click on "Heat up!", nothing happens, no request is sent when I examine the browser console, and I also cannot get any log output.
Can anyone tell me how to get the backend data to the front end so I can dynamically change the front end page?
Your script is not be getting called, your input is named heatit
but your jQuery is listening for a click on something with an id of heatit
. Try setting that id in your html and going from there:
<input id="heatit" name="heatit" type="submit" value="Heat up!">
If you would like to keep your html the same you can change your click listener:
$('input[name=heatit]').on('click', function(){
//your code
})
